ABSTRACr
The Montreal Protocol btipulates a complete phase-out of substances that deplete the ozonelayer. The Multilateral Fund has been established to providc grant finance to help developingcountries that are signatories to the Protocol to meet their obligations on an incremental cost basis.Other background papers set out the broad context; that is, the mechanisms and priorities of theFund and the role of national strategies to reduce ozone depleting substances. Within this broadcontext, this paper discusses the issues specific to incremental cost, the basis for eligibility forfinancing under the Fund.
The paper's aims are first, to highlight some of the remaining issues concerning eligibility forcompensation under the Fund and to propose, in the interim, a limited number of rules ofinterpreting in detail the principles which have already been laid down by the Parties, and second,to set out some of the operational implications which may need to be considered further in thecourse of policy development.
The first three sections comprise introductory and some background material which can beskipped by those familiar with the ozone issue. Section I introduces the problem, the mechanismet.tablished under the Protocol to deal with it, and the relevant aspects of the world industryproducing ozone depleting substance. Section II provides a framework within which the variousincremental costs, financial losses, and compensatory payments can be identified. Section III sets outthe circumstances that give rise to incremental costs. Broad categories of expenditure that are eligiblefor compensation by the Fund have already been determined by the parties to the Montreal Protocolat their London meeting 27-29 June 1990. These categories comprise the framework within whichincremental costs are to be identified and quantified. This paper continues the exploration of thenature of these incremental costs in the context of the structure of the industry and its markets, thevariety of country situations, and country policies.
Section IV interprets the incremental cost concept broadly (i.e., for countries), shows how thiscan be calculated, and identifies issues of eligibility for compensation under the Fund which may arisein future. While the important effect of country policies is noted, the design of appropriate nationalpolicies for implementing the Protocol is not covered in this particular paper.
Section V is the main focus: It interprets the incremental cost concept for individual economicagents (principally firms). The Parties to the Montreal Protocol clearly intend that the compensatorypayments under the Fund be made at this level. Principles for calculating these incremental costs areset out, and some unresolved issues of eligibility for compensation are identified.
Section VI concludes by coramenting on certain related operational matters: leverage, projectand financial cost focus of the Fund, and the relationship of the Country Program Framework Papersto project selection on an incremental cost basis. Some interim rules for application of the Fund'sresources are proposed.

INCREMENTAL COSTS OF PHASING OUT OZONE DEPLElTNG SUBSTANCES
I. INORQDUCTION
The Ozone Issue
1.1 Chlorofluorocarbons (CFCs) were developed as working fluids for refrigerators and air
conditioners, us blowing agents for foam manufacture, as specialist solvents, and as numerous other
sp,cialty chemicals. They were particularly useful compounds because they are very unreactive,
chemically and biologically, making them very stable, non-toxic, non-flammable, and non-corrosive.
They quicldy replaced other compounds (such as ammonia in refrigeration) that were much less
desirable. Similarly, halons, known for unreactivity and for poor electrical conductivity, were soon
established as fire extinguishants.
12 Paradoxically, this very desirable characteristic of unreactivity contnbutes to the present
problem concerning the destruction of stratospheric ozone CFCs, halons, and certain other long-
lived halogen compounds do not break down until they reach the stratosphere, where they ionize.
A series of chemical reactions are believed to release chlorine or bromine radicals that catayze
reactions that destroy ozone. Each of these chemicals can be characterized in terms of its ability to
do this by an index known as the "Ozone Depleting Potential" (ODP).
13 Ozone in the stratosphere plays an essential role in filtering out certain hamful ultraviolet
rays that would otherwise endanger human health and various ecological cycles. The ozone issue is
thus a global one with potentially serious implications.
The Montreal Protocol
1.4 The international community, reacting through the United Nations, recognized the danger
presented by ozone destruction and decided to limit the damage and the risk by stopping the
emissions of CFCs, halons, and substances having similar effecs This resolve took the form of the
Montreal Protocol, signed in September 1987. The Protocol is an agreement among nations which
establishes schedules for percentage reductions in the consumption of ozone depleting substances
(ODSs) based on use within each participating country during 1986. The Protocol also places
restrictions on trade in ODSs with non-parties to the ProtocoL
1.5 To facilitate the phase out worldwide, the developed countries established a special
Multilateral Fund (Fund) to provide financial assistance to the developing countries (defined in
Article V as those using less than 0.3 kg of ODS per head per year). The Fund would be used to
relieve the incremental costs associated with those countries phasing out ODSs.
ITe Structure of the World ODS Industry
1.6 The problem of phasing out ODSs is made a more manageable one by the following
characteristics of the world ODS industry:
* There are very few major manufacturers of ODSs. Production is dominated by six U.S.
and European multinational corporattIons. According to the latest issue of the Chemical
Economics Handbook (1990), Du Pont owns 35 percent of the world CFC production
capacity, followed by Atochem (18 percent), and Alli;;u Signals (13.8 percent). Together
with three other European multinationals (ICI, Hoechst and Montefluos), these firms
control over 80 percent of world CFC production capacity, with proprietary rights over
most processes. (See Table 1-1 for world CFC production and consumption.)
* There are only a few

based products in the
dominant (Le., industrialized country) markets is taking place rapidly. A trend noticeable
in some industrialized country markets has been the switch in market demand to
completely different chemical and raw material inputs (begun in the U.S. and Japan since
2
the late 1970s for aerosol products). Industrial analysts exptet that demand switching and
recycling could eliminate about 60 percent of the 1986 world CFC market. Based on the
Chemical Economics Handbook (1990), the replacements expected in the US. in the year
2000 are likely to be approximately:
- 30%o by hydrogen containing CFCs (HCFCs),
- 30% by recycling and conservation,
- 30M by nonfluorocarbons,
- 10% by fluorocarbons with no chlorine (HFCs)
* The specific question of phasing out ODSs in developing countries (principally CFC-11
and CFC-12) is simplified by the fact that few of them are producers. CFC production
in Mexico, Brazil, Argentina and Venezuela is controlled by the six major multinational
corporations through directly owned subsidiaries. In Asia generally, technologies have
been either licensed or sold to local firms in the private/public sector (although China has
developed its technology indigenously). The African market is serviced mainly by
European exporters of CFC products. According to the recently completed country
studies, all CFC producing developing countries (apart from China) are producing less
than 9000 tons of CFCs annually, with most plants reporting considerable unulized
capacity. There are a variety of user industries though, such as refrigerator factories,
which depend on CFCs either imported or locally made, and these will need to retool to
use the alternatives.
1.7 Table 1-2 indicates the size of CFC markets in developing countries. By world industry
standards production in any one of the developing countries appears uneconomic, and is vable only
because of protection by trade or tax policies. Table 1-1 and Table 1-2 together highlight the extent
of scale differences between producers in developing and industrialized countnes. In Meico, for
example, Allied Signals has two plants with a combined capacity of 14,000 tons per annum, and Du
Pont owns a plant with a production capacity between 4,000 and 7,000 tons per annum. The
international optimum plant size, by contrast, is 20,000 tons per annum. This suggests that the major
adjustment problem in developing countries is likely to be for user industries, rather than for
producers.

11. INCREM NTAL COST. COMPENAION. AND REIMBRSEMEi T
21 The purpose of this section is to make clear certain distinctions, as these will be imnortant
for understanding the calculational framework. Tbe distinctions are between:
* government and public costs;
* overall incremental costs borne by the country and incremental costs bome by individual
firms;
o economic incremental costs and financial incremental cots;
* expenditures and losses;
* incremental costs and recompense;
- principles for calculating the various types of incremental cost and the principles for
recompense
GermenOt and publc costs
2.2 Govnment costs. The government itself may incur (economic) costs in complying with the
ProtocoL For example the government might finance an information and advisory service, provide
worker retraining, invest directly in recycling plants and other associated infrvtructure, and bear
aous indirect costs (such as for road extensions) made necessary by the projects undertaken by the
enterprises All these government economic costs (gow) can be regarded as incrementaL
2.3 Public cost. The public at large bears economic costs in the form of welfare losses1 (A
welfare), such as those due to price rises, as well as in the form of incremental costs incurred by firms
(A privat) to comply with the ProtocoL
t Note that welfare loss could conceivably be negative, for example, where National Ozone Policyeffectively closes down uneconomic CFC-dependent enterprises that had been propped up by hightariff barrers or government subsidies.
S
Countrv and flim incremental costs
2.4 Country Incremental costs. The country incremental cost is the net economic cost of
compliance with the Protocol, calculated without reference to any presumed payment from the Fund,
A cwy (govt + A priae + A welfare)
where the summation is over all affected enterprises and relevant investments, The economic cost
of "capital abandonment" is reilected in the incremental costs of new investments made necessary by
the stipulations of the Protocol over what would otherwise have been the case.
2.5 Arm Incmental costs. An economic agent (such as CFC producer or a refrigerator
manufacturer) will incur private incremental economic costs (A private) as a result of the Protocol
stipulations. This incremental econominc cost will arise (i) from that part of the capital investment
and O&M expenditures on the substitute plant that is incremental to the original investment and
O&M expenditures and (ii) from the economic loss associated with the accelerated replacement of
the original plant.
Economic and financial incremental costs
2.6 Economic Incremental costs. These are real resource costs.
2.7 FincIal incremental costs. These are the costs which guide decision-makers at the firm or
consumer level because they include all the transfer payments (A trans):
Fnancial incremental costs to the firm
a A privae + A trans
6
The transfer payments will include thi incremental taxes and duties, net of incremental subsidies, that
are made to the government.2
Expenditures and losses
2.8 Expenditure. One component of incremental cost (economic or financial) will result from
the higher costs of substitutes. It is that part of the capital investment and O&M expenditure on the
substitute plant that is incremental to the original investment and O&M expenditure. Tbis
incremental cost will often be borne by the firm that made the original investment, but this need not
always be the case, e.g., if the original manufacturer closd and a new entrant invested in the
substitute.
2.9 Loss. Another component of incremental economic cost is the economic loss associated with
accelerated retirement of the original plant. For example, the closure of a plant before the end of
its normal economic life may impose incremental costs in the form of additional imports of substitutes
at a later stage or the earlier than expected investment in new capacity. Financially this is mirrored
by the loss suffered by plant owners as a result of the accelerated write-off.
Incremental costs and recomgense
2.10 Incremental costs. These are the various costs defined above and calculated without
reference to any recompense that may or may not be made.
2.11 Recompense. This can be made in respect of the incremental costs borne by firms individually
or by the country as a whole. The source would be an international transfer from the Multilateral
Fund, in the case where the recipient is a firm. Recompense can be conceived as comprising both
reimbursement (for the incremental expenditures) and compensation (for the losses) but this
distinction has no special importance.
2 There may also be incremental transfers to the public, e.g., additional financing charges andproduct liability payments, but these are probably not significant.
7
Pincins of calculation and principles of recompense
2.12 This report is principally concerned with establishment of principles for calculating the various
types of incremental cost. Principles for setting levels of compensation and reimbursement from the
Fund are matters for the Executive Committee.
2.13 However, to elucidate some options available to the Executive Committee, the following
alternative principles for compensation and reimbursement are set out.
(i) Country incremental cost. The Fund would reimburwse the government for country
incremental cost and call on the government to take care of all distributional aspects.
This is not the principle which is currently in operation, but may be appropriate if
larger transfers are contemplated in future.
(ii) Economic Incremental cost. The Fund would recompense governments for their
expenditures and firms for their incremental economic costs. Tbis is similar to the
Bank's usual project financing, since only economic costs are financed, not transfer
payments. Governments may wish to supplement the Fund transfers by waiving any
incremental transfer payments due to it from the firms concerned.
(iii) Fhiancal incremental costs. The Fund would recompense governments for their
expenditures and firms for their incremental expenditures and financial losses.

Il. INCURRING INCREMENTAL COSTS
3.1 Incremental costs in implementing the Montreal Protocol are incurred as a result of
transitions away from the use of a number of different ODSs, each with its own particular
applications and chain of production, use and consumption. This section is a brief technical
description of those features which influence the incremental costs of each of these transitions.
Production and Use of ODSs
3.2 ODSs. A range of ODSs has been defined in the Montreal Protocol (see Table 3-1). The
common feature in these compounds is that they are very stable and do not decompose readily until
reaching the stratosphere where they release ions of chlorine or bromine which can catalyze ozone
destruction. The most common ODSs in developing countries (accounting for 95 percent of ODSs
use) are the chlorofluorocarbons known as CFO-11 and CFC-12, generally used as refrigerants. To
a lesser extent methyl chioroform, carbon tetrachloride, CFC-113, CFC-114, CFC-115, halon-1211 and
halon-1301 are also used in developing countries. As time passes, the diversity of ODS use in
developing countries increases as their industrial sectors broaden. In the smaller less developed
countries, the commoner CFCs are used in refrigerators, air conditioners, aerosols and foams, but as
development proceeds applications broaden to include halons for fire protection, methyl chloroform
for metal cleaning and electronics manufacturing, and various CFCs for medical and specialist
applications.
3.3 Applications
(a) Reigeration and air conditioning. CFC (mainly CFC-12) are used as working fluids.
They are particularly attractive because they are cheap, non-toxic, non-corrosive and non-
flammable. Alternatives, while less ozone-depleting, are less attractive on one or other
of these grounds and their use will impose incremental costs. Refrigeration and air
conditioning are the fastest growing applications for ODSs in developing countres and
the rapid expansion of infrastructure and capital stock dependent on CFC technology will
lead to higher costs of CFC replacement in future.
(b) Foam blowing. CFCs (mainly CFC-11) are used to form polyurethanes, polystyrene,
polyolefin, and phenolic plastic products. The density of the foam can be altered by
9
mxing it with water. The low toxicity
and flammability of CFCs reduce the Tabl3-tConalroed Substaes under the Montreal Pocol
handling costs in an industrial setting. (A revised in June 1990)
However, relative to certain alternative * Group I: chlorofluorocarbons (CFCs) 11, 12 113,114, lS. These are carbon cmpounds

CFCs and have been increasingly used
instead in many countries. There is also strong competition from non-pressurized
packaging technologies such as pumps, pistons and brushes which are less costly but still
maintain satisfactory performance. In some countries, replacement of ODSs is complete
or almost complete (e.g., in Egypt, following a ministerial decree, and in Brazil, following
regulations banning CFC use in insecticides and household products, and also for
economic reasons). In other developing countries, the aerosol industry is not very
developed (e.g., in India, where traditional remedies and cosmetics are preferred and
where aerosol packaging attracts additional taxes). Replacement of ODSs is not likely
to be a major problem unless there is rapid growth in this industry.
(d) Solvent cleaning. CFCs and other chlorinated solvents such as methyl chloroform are
used in the electrical, metal cleaning, biomedical and various specialist markets. Non-
ODS solvents (such as water, alcohol and various other organic solvents) can sometimes
be substituted.
10
(e) Fire enguishing. Halons non-toxic, non-flammable, and non-conducting gases, have ideal
properties as fire extinguishants. They are generally used where fire is a direct threat to
human life and where no other agent could be effectively used. The principal ones used
are halon-1211 and halon-1301.
3.4 Sectors. The incremental costs associated with replacement of ODSs can be attributed to the
different sectors: production (new capacity or modification to or replacement of old capacity), user
(retooling in industries currently using ODSs), and consumer (premature obsolescence of consumer
durables and increased servicing or operating costs).
(a) Consumer sector. The refrigerator is a major long-term investment for those households
in developing countries that have one. Ordinarily one might expect that the phase out
of CFCO would impose heavy welfare losses, particularly on the middle income groups
(i.e., those who can afford a refrigerator but who are not otherwise wealthy). This is
because one can foresee that the inability to service the large and growing pool of CFC
refrigerators and the higher costs of replacements would impose direct costs as well as
other welfare losses on this class. While some studies (e.g., Box 3-1) point to this being
the case, the long lead-time (including an additional ten-year grace period for LDCs)
should imply that consumers can be warned well in advance and can take appropriate
defensive measures. Also, because large amounts of CFC are wasted during servicing of
refrigerators, and home refrigerator servicing is the largest net consumer of CFCs,
training in techniques of conservation, recovely and recycling should be able to reduce
these costs and welfare losses for a modest cost. Other losses (e.g., associated with
aerosol use) wil have veiy small impacts. It should be noted though that in some
countries (e.g., most African countries) the consumer sector is the only one impacted as
all CFCs and CFC-equipment are imported.
(b) User sectors. The user sectors comprise the manufacturers of refrigerators, air
conditioners, foams and aerosols, the industries that use ODS solvents, and the suppliers
of fire extinguishes Their direct incremental costs will be retooling to use alternative
chemicals and technologies or to make alternative products. A number of mid-sized
developing countries have user sectors in addition to the consumer sector (e.g., Egypt,
11
Tunisia, Turkey, and Yugoslavia), although they

also export ODSs to neighboring countries and may also import certain ODSs of a type
not made localy. In most cases there is considerable excess capacity, and much of the
plant is fully amortized
(d) Atbfic sector. Public expenditures on retraining, incormation programs, studies, databases,
demonstration programs, recycling and other infrastructure, and administration would also
be needed as part of an overall plan to phase out ODSs.
Factots Affecting Incremental Costs
3.5 A number of general factors will affect the incremental costs of the transition, apart from the
specific factors appling to individual ODSs. These are the role of market forces, the timing of
intervention in developing countries, expenditure on informational and administrative matters, and
the overall strategy adopted.
3.6 lMaret fores. The significant reductions in CFC use which have occurred to date in
developing countries have been market driven. In some cases the use of ODS alternatives has
actually been cost effective and operating costs have been reduced (e.g., in replacing CFCs in
aerosols). Export and local markets have been protected to some extent by the actions of industres
stopping the use of ODSs before being required to do so by bans. Where satisfactory alternative
technology exists, consumer preferences have been satisfied by non-ODS devices and preferences.
12
3.7 Increasingly, export markets will expect a powerful influence over the user sectors. Brazil,
for example, exports compressors to the US and elsewhere and Tunisia expects to export more than
half of its refrigerator production to Europe. The ODS bans and new standards in these large
markets (comprised of Protocol signatory countries) will by itself force compliance in the exporting
countries. Exports of foam products and aerosols will be similarly affected.
3.8 In the producer sector, the firms which are subsidiaries of the multinational chemical firms
or which operate under license from them will benefit from new technology developed in and for the
developed countries. However, where they exist alongside domestic competitors it may be necessary
to have government policy that "levels the playing field." That is, if the substitutes will be more
expensive there will be a market opportunity for an ODS competitor to continue operating until such
time as all firms are confronted by z ban.
3.9 Timing. The developing countries have been given a ten-year grace period under the
Montreal Protocol. That is, while developed countries are assigned a 1986 baseline consumption
(frcim which the percentage reductions are computed) developing countries can continue expanding
consumption until 1996 after which the reductions take effect. There is some evidence that this has
introduced a note of complacency in developing countries who do not feel the urgency which is the
spirit of the Protocol.
3.10 Illustrative growth rates for near term consumption of ODSs are given in Table 3-2. Whfle
the actions underway or planned in several countries will actually reduce ODS consumption, the large
consumers will expand consumption. The costs of delayed action will be high in countries where
ODS use is expanding dramatically (e.g., China, India, Brazil) because the capital stock that ultimately
requires modification or replacement would likewise be growing rapidly.
3.11 The India ODS country study indicates that if ODS elimination is not pursued vigorously and
immediately in countries with high growth in ODS use, the difficulty of ODS elimination will be
greatly increased. Data in Box 3-1, presented at a World Bank Seminar in October, 1990, indicate
that if implementation were delayed, overall incremental costs would increase by about 60 percent,
and consumer costs would increase six-fold in the course of about a decade. This results from
enormous growth in the domestic market for refrigerators and other CFC-using appliances which

alternatives are certain hydrofluorocarbons
(HFCs) or hydrochlorofluorocarbons (HCFCs)
which have much lower potential for depleting ozone.
3.13 User sectors
(a) Refrigeration/air-wondiioning
* Recycling and reclamation involves expenditure on new equipment (tanks, purifying
equipment etc.) and retraining.
* Chemical alternatives (such as HCFCs, HFCs, ammonia and other fluids with low ODP)
involve retooling costs in the factories, new handling facilities because of toxicity or
flammability (case of ammor;S), or new bulk facilities and chillers, depending on the
actual substitute.
14
* Alternative technologies, operating on a different cycle or with different configurations,
are capable of using non-ODS working fluids. The costs are redesign, retooling, and
retraining.
(b) Foams
* Recycling and reclamation can be achieved in the curing area (a major source of CFC
emissions during manufacture) through a process known as carbon adsorption. This
process is expensive though.
O Chemical alternatives such as HCFC-123 and HCFC-141b are possible substitutes,
although there are others including hydrocarbons. Incremental costs will be incurred on
plant modification, e.g., to handle the flammability of the agents.
* Alternative technologies are needed to compensate for the slightly poorer insulation
properties of the foam produced by chemical alternatives. Costs will be incurred on
modifications to pumps, pipes, filters, etc. Technologies also exist to reduce or even
eliminate the CFC used as a blowing agent.
* Product substitutes may also be developed in time, such as vacuum insulation panels to
replace foam. Greater use might also be made of natural and synthetic fiber materials.
(c) Aerosols
* Chemical alternatives, such as deodorized LPG, are available. There will be costs of
providing supply facilities for the deodorized gas and for handling a flammable gas in the
manufacturing process. This is alread'y cost effective. HCFCs could also be used.
* Alternative technologies, such as mechanical atomizers, have been available since before
the time that aerosols were widely used, and are still acceptable in many cases.
* Product substitutes, like brushes for cosmetics, will also be used.

(d) Solvents
* Conservation and recovery practices can dramatically reduce the ODS use in electronics
manufacture. Management costs and the costs of engineering controls will be incurred.
In the metal cleaning sector, recovery techniques have been available for many years.
Capital expenditure would be needed for gravity separation, water adsorption, or single-
plate distillation equipment.
* Chemical alternatives exist which in many cases provide equal or better cleaning
performance at equal cost to CFC-113. Methyl chloroform and carbon tetrachloride
could also be used and, although they are substances controlled under the Protocol too,
their ODP is much less. Certain other organic solvents substitutes which are volatile
organic compounds may be undesirable for local environmental reasons.
* Alternative technologies for cleaning such as ultrasonics, aqueous immersion etc. are
available.
3.14 Consumer sector. Increased costs here will lead to premature replacement of CFC based
reErigerators and air conditioners, higher costs for service calls where technicians have to use special
techniques to avoid wasted CFC, and perhaps disposal costs for old appliances. Note that in any
overall assessment of compliance costs double-cunting will have to be eliminated, i.e., incremental
economic costs of recycling cannot be simultaneously assigned to both the service company and the
consumer.

IV. INCREMENTAL COSTS TO COUNTRIES
Country Incremental Cost Approach
4.1 Country incremental costs can be divided into economic costs met by government and
economic costs borne by firms and others. One possible way in which a compensatory mechanism
might operate is that countries are reimbursed for the minimum country incremental cost necessary
to meet the phase-out schedule, and that the country concerned subsequently take responsibility for
the distributional issues within its borders. The government would need to adopt a National Ozone
Policy which, first, attempted to minimize the overall adjustment cost and, second, ensured equitable
distribution of the adjustment burden and the compensatory payments among the various economic
agents. This section covers the calculation of country incremental costs and highlights the issues
concerning compensation/reimbursement to countries.
4.2 In principle, three estimates of country incremental costs could be given, and should be
distinguished. The first is the mnimum incremental cost which would be incurred if the country met
the Protocol targets by adopting the most efficient policies possible, e.g., removed price distortions
and rationalized industry and trade policies where necessary. (This 'cost' might well b.- negative in
some cases.) The second, which could be called the compliance cos.% is the incremental cost which
would be incurred against the background of existing economic and industrial policies by adopting
only the most efficient policy that is specific to the phase out. (This cost could not be completely
defined until the boundary between the specific and the general policies has been drawn.) The third,
which could be called the adjustment cost, is just the actual cost incurred, ie., it exceeds the
compliance cost to the extent that adjustment is inefficient.
Effect of Countra Policy
4.3 Economic and industial poUcy. Compliance cost, as defined above, is thus strongly
influenced by general economic and industrial policies. Since it is not the intention of the Parties to
require general economic or industrial policy reform as a condition for assistance under the
Multilateral Fund, it is only compliance cost and not the true minimum incremental cost that needs
to be calculated. However it may be worth noting the extent to which a country's general policies
will influence the cost of compliance. An extreme example would be the case of a country that had
17
encouraged small-scale, inefficient domestic production of CFC behind high trade barriers; in this case
merely prohibiting CFC manufacture would actually remove a distortion and could incur a negative
adjustment cost. (Outright prohibition may not be the most efficient adjustment mechanism though,
and it is still worthwhile examining alternative strategies to reduce the adjustment inefficiencies.)
4.4 Key aspects of the countty's economic and industrial policies that will affect compliance cost
are:
* The country's development strategy (e.g., degree of outward orientation);
* Industrystrategy (including trade protection and restrictions on ownership and competition);
* Regulatory and incentive structure (including legislation and the tax structure); and
* Institutional capacity to implement regulations.
4.5 National Ozone Poliy. In addition to any compliance cost there will be inevitable additional
costs introduced by inefficiencies in the adjustment process. One purpose of the government
adopting a national strategy for protection of the ozone layer (the "National Ozone Policy" referred
to earlier in Section II) would be to minimize these inefficiencies. The distinction between
compliance cost and inefficiencies in the adjustment process is useful because these costs are related
to different policies (the pre-existing industrial policy on the one hand, and the National Ozone
Policy as implemented on the other) and can be controlled in different ways. It might otherwise be
easy to lose sight of adjustment inefficiencies in cases, such as the example given above, where the
compliance cost is negative but partially offset by costs arising out of inefficient adjustment.
4.6 National Ozone Policy would make use of a combination of policy instruments specifically
targeted on the phase out. The following key instruments illustrate the difference between National
Ozone Policy and general policies:
* Quotas and bans on the production and use of particular ODSs;
18
o Sales of permits for the production, importation or use of particular ODSs;
* Fnancial compensation for closing ODS capacity, e.g., from the government or through the
Fund;
* Fnancial assistance to establish new plant or modify existing plant to manufacture or use
substitutes;
* Taxes on sale or disposal of ODSs, ODS-using equipment, and products whose manufacture
required ODSs;
* Subsidies on substitute products and equipment;
* Infrastructural support, e.g., for recovery and recycling of CFCs or for transport, storage and
disposal of substitutes;
* Retraining, promotion, and technology transfer.
4.7 One important criterion for judging of National Ozone Policy will be adjustment efficiency, but
another will be fairness since the effect of policy will be to redistribute the burden of adjustment
among the various sectors (producers, users, and consumers). The redistributive effects may also
affect the incentives for compliance.
Calculating Compliance Cost
4.8 The compliance cost (i.e., minimum adjustment cost given existing economic and industrial
policies) can be determined, at least in principle, from a least-cost plan of adjustment comprising an
optimal National Ozone Policy together with an optimal investment plan. The principle is to
minimize the incremental economic costs subject to the constraints defined by the obligations under
the Protocol and by the general policies of the country. In essence the economic problem is similar
to that of developing a least cost investment program for (say) the power sector. Electric sector plans
begin with demand forecasts and a range of technical options that meet the demand. Total capital
and operating costs, appropriately discounted, are minimized using an algorithm that determines the
19
selection and timing of feasible investments subject to a variety of imposed constraints. The
reasonableness of initial assumptions concerning demand (a function of price) can be tested by
extracting estimates of supply costs from the calculation. If necessary, these assumptions can be
revised and the whole calculation can be performed iteratively until a desired degree of consistency
and convergence is reached. Likewise, in the case of ODS phase out, costs need to be evaluated in
a dynamic framework, a program with a time dimension for each of the sectors involved. Consumers'
incremental costs, for example, would include those incurred over the economic life of CFC-based
refrigerators due to "premature" replacement, increased energy requirements, and higher recharge
expenses, followed by the earlier subsequent replacement of the following (substitute) refrigerator.
User firms may experience one-time retooling costs followed by continued higher operating costs.
Producers too would need to alter the selection and sequence of investment projects and operations
over a period of time.
4.9 However, in the case of ODS phase-out, there are several special features to take into account
which make the problem more difficult than least-cost programming in other sectors. The first special
feature concerns a compensation principle which, when it is agreed, should be reflected in the choice
of the "without Protocor scenario that is being contrasted to a "with Protocol" scenario in order to
arrive at an estimate of the incremental economic cost. These scenarios are not always clearly spelled
out, and this cart lead to confusion. In the "without" situation, a choice has to be made whether
losses connected to trade with developed countries who have ratified the Protocol are included. So,
for example, if we wish to compensate a developing country because it will lose export markets or
incur incremental costs in making its export goods suitable for countries which have signed the
Protocol, then we need to define our "without" scenario as the one representing what would have
been the case if none of its trading partners had imposed any of the Protocol's restrictions on trade
or on specifications for use of imported ODS equipment within their own internal markets. If, on
the other hand, we regard trade losses as non-compensable, our "without" scenario must assume that
developed countries have ratified but that the LDC in question has not done so yet.
4.10 The second special feature concerns a technical question in constructing the "with" scenario.
The question is whether the cost structure (at-d hence the price signals and resulting demand
patterns) have been seriously affected either by the Protocol restrictions or by assumed levels of
compensation (whether government transfer payments or grant finance from the Multilateral Fund).
20
To do a least cost analysis (rather than an analysis where both costs and benefits are fully integrated)
it is necessary to assume that benefits, including those resulting from the use of ODSs or their
substitutes are the same, i.e., that the level of services provided by ODSs in the "without" scenario
are the same as those provided by substitutes in the "ith" scenario. As the Protocol specifies fixed
targets, it also assumes implicitly that any of the "with" scenarios meeting these targets will deliver the
same global benefit.
4.11 The third special feature is that the demand for the services of existing ODSs must be
disaggregated by ODS. There are six groups of controlled substances defined by the Protocol, each
with its own chemical properties, type of use and sector of application. In principle, one should
compare total cost and benefit streams obtained in an integrated framework, (i) using the benefits
specific to the reduction of each particular ODS, say by weighting emissions in terms of their Ozone-
Depleting Potentials, (see Table 4-1),' and (ii) discounting future benefits of reduced emissions,
which would value more highly the earlier reductions and encourage earlier compliance. In practice,
the Protocol stipulates phase-out schedules for the substances and hence the reduced benefits of
ozone depletion are fixed, only the costs need to be minimized. Furthermore, the phase-out
schedules are applicable on a group basis: this means the problem is the sum of six separate reduction
strategies with no tradeoffs allowed between substances in different groups.4 Ideally one should trade
off reduction rates among all the ODSs antil the marginal benefit of a unit reduction in ODS is the
same for all' Also, because the Protocol stipulates reduction targets (e.g., a 50 percent reduction on
baseline consumption for Group II ODSs by year 2006) there is no acknowledgement of any
additional discounted benefits resulting from earlier than normal compliance.
I Because of some scientific uncertainties and data gaps on proposed weights (such as OzoneDepleting Potential and Chlorine Loading Potential) this may not be practical in all cases.
4 Within groups, tradeoffs are implicitly allowed as the consumption subject to control under theProtocol is calculated as the ODP-weighted sum of consumptions in each group.
' While there is some flexibility of substitution within a group (eg., reducing relatively morehalon-1211 than halon-1301 while still maintaining the overall target reduction for Group II as awhole) substitution between groups is not credited for compliance purposes, even between groupshaving the same target reduction profile.
21
4.12 The fourth special aspect concerns data adequacy.Table 4-1

at present using CFC-11 and CFC-12. There is,
therefore, considerable uncertainty about whether the substitutes will be able to benefit from the
same economies of scale as the existing ODS. In any case, the decline in prices of ODS substitute
manufacturing and utilization equipment would also depend on economies of scale in production in
industrialized countries. Markandya (1990) notes that CFC prices in the past have declined by
constant percentages each time production doubled and cites industry sources to desribe this
relationship -- the price elasticity with respect to cumulative production -- to range between -.02 to -
.03 for CFCs. As the substitute products are being developed by the same multinational firms (Du
22
Pont, Atochem, Allied Signals, ICI) which are price setters for specialty chemicals world-wide, one
could expect past trends to continue.
4.13 The fifth special feature is that the costs of ODS phase out will be highly distributed; they are
not borne by one or two utilities or corporations but by a variety of producers, users and consumers.
There may also be costs imposed on the govemment in the form of incremental administrative costs
and additional infrastructure, and on the economy as a whole to the extent there is (say)
consequential unemployment, although these may not be large (or easily quantified).
4.14 Finally, since we are interested in incremental costs, the calculations of cost have to be
performed twice; once for the least-cost, Protocol constrained (or "with") solution and once for the
unconstrained (or "without") case. Incremental cost is the difference in cost between two scenarios.
4.15 The analysis requires a projection of demand for ODS services, a description of the constraints
placed on individual ODS use (i.e., phase out profiles), a technically feasible program of appropriate
substitutions and alternative technologies to meet the demand for ODS services within the constraints
set for the ODSs themselves, cost data on the current technologies and the alternatives, and the
choice of the least-cost approach. (See Box 4-1 for a summary of these steps.)
Step 1: Demand projections
4.16 The projected demand for the serices required of ODSs/ODS substitutes is required. Current
ODS use may need to be ascertained from industry survevs or analyses of existing statistics if
available. Projections can be made on the basis of near-term expectations of industry leaders and
current users and projections of industry development.
4.17 Ideally the comparison of the "with" and "without" cases would be performed in a general
equilibrium framework to capture all the tradeoffs and the full adjustment costs to the economy. In
particular this would require different demand projections for the baseline and phase-out scenarios
and a measure of the benefits of ODS reduction. If a country adheres to the Protocol, the use of
higher price alternatives will of course alter the demand for the services provided by ODS alternatives
and the adjustment costs will be diffused throughout the economy. (There will also be costs
23
associated with unserved demand, since one might
expect that the implementation of a substitution n
program will not always be smooth.) Calallu Countt COSUpIJ CosStep 1: Project demand for ODS,

propellants (where the alternatives are already
competitive) and solvent cleaning (where ODSs and their substitutes are responsible for only a small
fraction of total production costs in the industry concerned) this is likely to be a good approximation.
In other cases (perhaps air conditioning/refrigeration), price rises will affect demand. For example,
the substitute for the CFC-12 currently used in refrigerators will be more expensive than CFC-12, and
the equipment using it will also be more expensive than the prevailing models, at least initially. The
higher cost of refrigeration will depress the demand for refrigeration somewhat. Incremental costs
for importing the alternative fluid and converting (say) a refrigerator factory to make equipment that
uses it should be based on the demand expected at the higher price.'
Step 2: Constraints
4.19 The problem is one of constrained cost minimization: the costs are the incremental costs and
the constraints are the series of phase-out schedules for each ODS. See Table 4-2 for the constraints
stipulated for Article V countries (developing countries). Other constraints may exist due to the
exsting general policies.
6This effect is calculated prior to, and partly as a justification for, compensation for the increasedcapital and operating costs available from the Fund. Of course this compensation itself (and anygovernment transfers) will alter the financial costs bome by various groups and may alter the priceand demand structure for ODSs and related goods.

Steg 4: Alternative scenarios
4.21 There may be several different feasible ways of obtaining the desired reduction. These should
be speifiae
25
Step 5: Incremental Costs
4.22 Costs will arise in the different sectors -- producer, user and consumer -- and may be passed on
from one sector to another. There are four important analytical issues: ensuring no double-counting,
recognizing costs at the time they are incurred, discounting, and treating premature obsolescence.
4.23 Double counting. Incremental economic costs recognized as having arisen in (say) the producer
sector cannot also be regarded as incremental costs in a user sector if they are passed on in the form
of price increases.
4.24 Timing. Ihe calculation is an economic not a financial one. It is appropriate to include costs
as they are incurred beginning with capital expenditure and continuing with incremental operating
costs and overheads in each year of operation. Depreciation is not included as the capital cost of the
plant or modification is included and the discounting of future expenditures makes an appropriate
allowance for the return on capital.
4.25 The timing of investments may turn out to be a very important aspect of the strategy.
Developing countries may be able to benefit by delay because of unit cost reductions that occur later
when the global market for substitutes has expanded to the point where economies of scale are
realized or when developed countries have wrought significant technical progress. On the other hand,
in a rapidly expanding domestic market, delay could increase the size of the capital stock requiring
premature replacement, as suggested by the results of the study on India shown in Box 3-1.
4.26 Dscounting. Future economic costs need to be discounted. A typical real discount rate of 10
percent p.a. may be used unless there are compelling country reasons for selecting an alternative rate.
4.27 Premature obsolescence. By projecting future incremental economic costs and discounting, the
economic loss arising from any premature obsolescence of plant is taken into account as the cost of
having to modify plant and equipment or to replace them with new technology alternatives.
26
Step 6: Least cost
4.28 The scenario with the lowest incremental cost should be selected. This cost is the "compliance
cost." As it is unlikely that sophisticated linear programming techniques can be supported by the
available data, this step would probably be performed by inspection and adjustment.
Compensation and Reimbursement Issues
4.29 Several issues concerning compensation are highlighted by this discussion that merit
consideration in any future re-interpretation of the eligibility principles of the Fund:
(i) Is compensation to be made on the basis of some calculation of overal "countly
inremental cost"?
(ii) If so, is the compensable amount the "compliance cost" (Le., the minimum adjustment cost
possible given the pre-existing generally applicable economnc and industrial polcies) or the
actual "adjustment cost"?
(iii) Are costs due to markcet-induced changes compensable? Whether or not a country joins
the Protocol it will suffer incremental costs due to the change in international market
conditions. In the example given earlier, a compressor exporter such as Brazil would
find that export markets in the United States will close unless the exported equipment
meets new requirements for the ODS alternatives being adopted by the United States
as a Protocol signatory. As another example, an Eastern European country, depending
entirely on imported CFCs for a local refrigerator factory, wou!d suffer the costs of
transition if trade in CFCs is successfully reduced by the concerted action of signatory
countries. These losses may be sudden and direct (e.g., closure of factory because of
sudden loss of existing export markets) or longer term (e.g., loss of expected market
development). Eligible costs certainly include all self-imposed costs (since Fund
compensation is intended as an incentive for countries to join) and, as a concession on
equity grounds, might conceivably be extended at a later date to include short-term
27
trading lossese (due to import and export bans, and the increased cost of imported
substitutes).
(iv) Over what time hoizon are costs compensable? For the cost calculations, projected
demands are required until at least the year 2010 (the phase out date for developing
countries). A longer period would be needed if the discounted value of incremental
costs continuing beyond that date are expected to be significant. Although this is
unlikely given the economies of scale and the technical progress possible within the next
twenty years, the principle for compensation should be clear lest there be cases where
significant losses continue past the phase-out date.
4.30 There are also 'follow-up' issues, so characterized because they are not so much matters of
interpreting eligibility, but matters for consideration if there is any restructuring of the Fund. One
such issue is that of how to encourage phase-out of ODSs earlier than currently scheduled, where
the cost of doing so is modest.
I Those that are incurred before (say) 1995. 'Short term' is an arbitrary period reflecting theinability of firms to make immediate adjustments to sudden changes in order to avoid losses. Thejudgment wil have to take into account the economic life and alternative uses of production capacitydedicated to serving export markets.
28
V. INCREMENTAL COSTS TO FIRMS
5.1 An alternative way in which a compensatory mechanism might operate is that individual
economic agents ("firms") are reimbursed for their incremental expenditures and compensated for
their financial losses by some combination of the Fund finances and government transfers. (In fact
the London Agreements, which clarified aspects of the Multilateral Fund, have a definite project
orientation that clearly indicates this is the approach to be taken initially. See Appendix.) This
section covers the calculation of such incremental costs. Refer to Section II for distinction between
the incremental expenditures and the financial losses, the latter acting as a proxy for the economic
loss of early plant closure.
Similarities to and Differences from the Country Incremental Cost Approach
5.2 Many of the issues that arise in the calculation of incremental costs to individual economic
agents (referred to as "firms" for convenience) also arise in the case of countries (see Section IV) and
are not repeated here. For example, in attempting to calculate the least cost adjustment path of a
firm over a given planning period, one would encounter similar problems of data adequacy, baseline
definition, and degree of disaggregation needed.
5.3 However there are some important differences from the case of country incremental costs:
(i) Decision-makers in firms are guided by costs that are financial rather than economic.
This makes it important to decide on a principle for reimbursing transfer payment
component of incremental expenditure and compensating for financial losses.
(ii) Fmancial costs of the firm may be greater than or less than economic costs of the firm.
(iii) The analysis of incremental costs of the firm is at best partial, it leaves out associated
government expenditures (e.g., on retraining) and external costs.
(iv) Total country incremental cost will likely be very different from the sum of the financial
incremental costs of all eligible firms because the latter includes varous transfer
elements and excludes costs borne by the public.
29
(v) Finally, complex questions of distribution will arise: the incidence of the initial
adjustment costs, the impact of adjustment policies and payments, and the passing on of
incremental costs from one group to another through price changes.
Effect of County Polica
5.4 The differences in approach can be illustrated by an re-examination of the impact of country
policies (this was discussed earlier in connection with country incremental costs in Section IV).
5.5 Economic and industrial policy. General economic policy (e.g., on taxes and duties, fuel
subsidies etc.) significantly affects private financial costs (as shown by the example in Box 5-1).
Incremental financial and incremental economic costs differ substantially due to transfer payments
and costs borne externally by the government and the public at large, as shown in the "balancing"
column in the example. Industrial policy that offers generous depreciation provisions is a particular
policy that can make a substantial difference (see example in Box 5-2).
5.6 National Ozone Policy. National Ozone Policy seeks to implement the Protocol and, in the
process, may redistribute the incremental costs between groups. This will have to be considered in
the calculation of the incremental costs actually experienced. For example, ozone tax credits or
subsidies will lessen the burden for some, perhaps even affecting the incentive structure and the
demand. (As mentioned, one important part of National Ozone Policy will be the provision of a
'level playing field," so that those firms undertaking incremental investments for compliance purposes
will not be disadvantaged in a competitive market for their goods and services vis-a-vis more tardy
firm.)
Calculating Incremental Costs to Firms

the firm level,

amortization, salvage value, and the appropriate private rate of discount. But in addition, there are

for the usual reason that the present value of such a benefit will reduce the incremental

Then

Let a = amortized fraction of the original investment
S = salvage value of plant (including any tax benefit of the residual amortization)
L = financial loss due to the Protocol
TMe financial loss is the unamortized fraction of the original investment less the salvage value,
that is
L = I (1-a) - S

financial loss.

is not fuly utilized. In such a case
33
- the incremental expenditure due to the Protocol would relate only to the replacement of
the utilized capacity; and
- the financial loss due to the Protocol would be less than the overall loss which also includes
the pre-existing loss due to overestimated demand.
Let
c = fraction of original capacity utilized
Then
E ='-cl) + r (M-cM)
and
L = c [I (1-a) - S]
where the salvage value has been prorated between the utilized ana unutilized capacity. Thus the
incremental cost would be
E + L (I-caa) + r (M'-cM) - cS
5.13 Capaity expanlon and plant modernization. A second complicating factor arises when the
replacement plant exceeds the capacity of the original because the manufacturer wishes to supply a
larger market. In such a case
- the incremental expenditure due to the Protocol would be less than the total which also
includes expenditure needed for capacity expansion; but
34
- the financial loss would be unaffected.
Let k = ratio of old (utilized) to new capacity
Then
E (kd'-) + r (MW/-MA
and
E + L =(-ai) + r((kW-* - S
Similar considerations apply in the case of plant modernization because not all the incremental
expenditure can be attributed to replacing exsting capacity.
5.14 Overall caculation. Combining both original overcapacity with capacity expansion, the
incremental cost is given by

Compensation and Reimbursement Issues

compensable share of the
pre-existing utilized capacity among them. For example, if Firm A with utilized capacity
of 100 closed and Firm B and Firm C both entered the substitutes market with capacity
100 and 50 respectively, only a proportion of the capacity of B and C would be a
replacement of ANs capacity, the rest would represent capacity expansion for which
reimbursement may not be eligible. Some allocation principle would thus be necessary.
(ii) Would reimburement be reduced to the extent that costs are passed on? Under
competitive conditions, compensation for financial loss only would not distort the market
for substitutes: investment in substitutes would be equally attractive to the compensated
firm and new entrants which would pass on the costs of making or using the substitutes
to the users and consumers. However, if the incremental expenditures are reimbursed
as well, either the price of substitutes will be kept artificially low (assuming a competitive
36
domestic market) or (in the case of imperfect competition) the fim could be
overcompensated: fully by the Fund or govermnent and at least pardy again by passing
on the incremental expenditures. Under the imperfect market conditions in many LDCs,
firms compensated for incremental expenditures are likely to be overcompensated to the
extent they can also pass on such costs.
(iii) Would compensation reimbursement be reduced to the etent that losses and costs can
be covered by a multinational partner in a joint venture or wholly owned subuidiary
conpany?
(iv) What part of the compensation and reimbursement due a finn should be met by the
concerned government? The total compensation received by the firm would comprise
payments from the Fund and additional payments from the government as a
consequence of its National Ozone Policy. The division between the two needs to be
made clear. One possibility, suggested in Section II, is that the government waives
additional transfer payments due to itself (e.g., incremental taxes).
(v) Can reimbursement be retroactive in a situation where a fim chooses to invest in
substtes as soon as possibk?

VI. OPERATIONAL CONSIDERATIONS
Context
6.1 The operational context comprises the provisions of the Protocol, the decisions of the Executive
Committee of the Multilateral Fund, and the Bank's usual procedures. The current exigencies and
strictures of the Fund define the character of the "Pilot Phase," within which a number of departures
need to be made from the ideal way of computing incremental costs (described in Section IV and
Section V). The possibility is left open, however, for a longer term approach which, based on
substantially greater resources, could more closely approach the ideal. The operational considerations
in the Pilot Phase and their implications for incremental cost calculations are set out below.
Leverage
6.2 The total allocation of funds in the Pilot Phase is limited to $240 million. It is clear therefore
that the availability of funds for any one country is small. Thus it is not possible to obtain any
general policy reform and existing distortions will have to be accepted as part of the background.
Developing countries will also resist policy conditionality on what is seen as compensation rather than
development assistance. At the Second Meeting of the Parties in June 1990 it was decided that
financial and technical assistance would take into account the national industrial strategy of the
recipient party.
6.3 The implication of this is that the Fund cannot be used to achieve general policy reform.
National Ozone Policy is still required to facilitate the phase out, ensure efficient adjustment, and
provide necessary support for individual projects, e.g., by providing regulations on phase out so that
firms making the necessary incremental investments are not penalized in the marketplace. It is also
clear that the thrust of project selection should not undermine policy reform being undertaken for
other reasons, e.g., where an economy is already in transition from a "command-and-contror industry
strategy to an incentive-based system. In this case, task managers may wish to avoid production-
oriented projects and emphasize investments that shift demand. (Tbis issue concerns project selection
and the content of National Ozone Policy, which are not the main focus of this paper.)
38
Focus on Projects and Financial Costs
6.4 Another aspect of the operational context is the project focus given to the Fund by the Parties.
Financial assistance is to be provided not only in relation to specific projects (for which eligibility
criteria have been devised) but also for defined categories of eligible incremental expenditures.
(Eligible categories of expenditure, defined in the London Agreements, are attached as Appendix)
Certain costs other than project-specific incremental costs may also be incurred under other functions
defined by the Parties to fall within the purview of the Fund (e.g., clearinghouse functions). However
these are relatively minor. These costs could include studies, distribution of information, workshops,
training, and coordination.
6.5 One implication of this is that initially the Fund will not compensate countries for overall
economic compliance costs, as calculated in Section IV, but individual firms (or state corporations)
undertaking specific eligible investments. A second implication is that this compensation is made for
incremental financial costs, since it is financial incentives to which these agents respond. (The total
compensation payment could however be made partly from govermnent sources and partly from the
Fund.)
Count Program Framework Paper
6.6 The general objective of the Country Program Framework Paper (CFP) is to provide an
integrating framework for ongoing and planned studies, policy analyses, investment and other project
preparation.8 Among other things the initial CFP would describe briefly the indicative and prioritized
investment program for ODS reduction and the strategy for implementing the Protocol (i.e., the
initial National Ozone Policy).
6.7 Eventually, an updated and refined CFP would contain sufficient information to estimate overall
compliance cost (which would assist country programming) and to rank alternative measures in terms
of their cost-effectiveness even if a comprehensive economic cost minimization (such as descnrbed in
Section IV of this paper) is not possible. General economic and industry policy is taken as a given
I A more detailed account is provided in the companion document, "Country Program FrameworkPapets" (CFPs).
39
but the investment prograhi should be supported by a National Ozone Policy which aims to keep
adjustment costs as low as possible.
6.8 The outputs of the CFP would be used by Bank staff as follows:
O The project rankings would be used to select projects for appraisal.
* The estimated compliance cost of the program could be used as one criterion for
determining total Fund assistance to that country.
* The attribution of incremental costs to various sectors and firms would be used to avoid
double-counting and possible over-compensation. For example, incremental costs of imports
would not also be attributed as incremental operating costs for various industries. The role
of National Ozone Policy (in relation to transfer payments and to any constraints on the
affected groups' ability to pass costs on) is crucial in this regard.
Ponsed Interim Compensation and Reimbursement Rules
69 Prior to specific consideration by the Executive Committee of the issues in compensation and
reimbursement highlighted in this report, a small number of interim rules are proposed for the Pilot
Phase which are consistent with the general thrust of the existing agreements among the Parties to
the Fund:
(i) Compensation from the Fund is made for once-only financial losses at the firm level
(ii) Reimbursement from the Fund is made for once-only incremental capital expenditures
and for the present value of the incremental O&M expenditures for the ensuing three
years (both net of incremental taxes and duties) at the firm level, and for direct
incremental expenditure at the government level over the next three years.
(iii) National Ozone Policy as a minimum should
- demonstrate how Protocol targets will be met;
40
- show how the instruments selected will minimize adjustment coSt;
- allocate the "replaced capacity' among new entrants where necessary; and
- address other distributional issues arising out of the adjustment process or out of the
compensation and reimbursement payments.
(iv) Financial loss and incremental expenditures are to be calculated as set out in Section V
of this paper.
(v) Eligible categories of incremental cost are as set out in the London Agreements (refer
to the Appendix to this paper).
6.10 Nothing in the above precludes the possibility or diminishes the desirability of adopting the more
fexible and efficient country incremental cost approach in due course. Perhaps the time to consider
this is when more experience has been gained by the implementing agencies and when the Fund
resources available more closely match the total financing requirement. At such a time, the losses
to the Fund from an inefficient approach would be much higher than they are now and less offwet
by any benefits such as "incremental experience."
